Canada is not alone in seeking jobs through asbestos mining. Here is an article on political upheaval as connected to the Shabani Mine, which is said to contain enough asbestos for 17 more years of production. Articles on history related to the mine are here, here, and here. Turner & Newall once owned and ran the mine, as described here. Drawing from the Turner & Newall papers, Jock McCulloch wrote this detailed article on how Turner ran the mine. A later, broader paper by McCulloch is here. More Turner history is here. There also is a government study of the mine.
